Abstract: 22,871. Boult, A. J., [Johnson Typesetter Co.]. Nov. 12. Type, setting and distributing. - Ejectors 123, 125, Fig. 3, deliver type from lower and upper case magazines having lower fixed channels 103 and upper movable channels 104, to assembling - aprons 122, 124, which may be single aprons with guide - ribs 163 leading to common delivery points on a travelling belt 166, or may consist of several sections or funnels delivering one behind the other. A common ejector-bar 131 is connected by links 132, 133 to a rock-shaft 134, in turn linked to a crank 137, Fig. 7, on a shaft 138 carrying a pawl 142 adapted to be engaged with or disengaged from a crown-wheel 141 on a rotating shaft 139, on operating a cam 143 and slide 144 from a universal bar or bail 152 over the rear ends of the key levers 153. Lift rods 154 normally rest on a shelf 155, and are operated by push-rods 159 from the key levers, and returned by a rocking-blade 160 operated by an arm 161 engaging a pin 162 on the link 133. The belt 166 runs over a drive pulley 167 and sheaves 168, 169, the later connected by a rod 170 to an elevator slide 171. Figs. 3 and 10, carrying an elevator-lifting pawl 177, a pin 178 on which travels in a slot in a trigger lever held by a spring in the path of the type, and thrown out by means of a cam on the slide. An elevator 175 normally stands with the upper ends of its prongs just below the point of delivery of the type, and is adapted to carry the type past a pair of spring retaining-pawls 186 of the stick or assembling- channels 172. The delivery of type from the belt may be regulated by a pawl provided with a type stop and vibrated in unison with the slide 171. The type are held in the stick by a pivoted arm 188, pawl 189, and yielding slide 187, and are assembled with separators 191 between the words. A latched swinging block 208 allows access to the channel 172, and a bolt 211 connected to, the latch normally holds back the pawls 186, but, on being withdrawn, releases them so that they form a platform for the type during inspection &c..A starting-lever 192 operates, through a bolt 193 and a pin 194 in the line-lifting rack 195, a pivoted arm 196, an arm 197 of which passes under the type in the stick, a gravity pawl 198 dropping and holding the arm 196 against the action of a spring 199. At the same time a latch 200 is withdrawn from the rack, allowing the latter to be raised by a train of gears, one of which is on a shaft 205, Fig. 17. A pinion 235 on this shaft, meshes with a heavy rack, a pin on which is adapted to engage an arm 237 on the rock-shaft 223, Figs. 17 and 24, and start the line shaft 219 and space shaft 225. Gear 217 on the sleeve 216. on which a driving- pulley 212 is mounted, meshes with gears 218, 224 loose on the shafts 219, 225 respectively. A pawl 220 on the shaft 219 tends to engage a ratchetwheel 221 on the gear 218, and is operated by means of a cam arm 222 on the rock-shaft 223. A pawl 227 on the shaft 225 is similarly operated from a rock-shaft 229, in turn operated by an arm 230 extending into the path of an arm on the shaft 219, an arm 232 on a rock-sh.ft 233 latching an arm 234 on the shaft 229. A pulley connected to the pulley 212 drives the shaft 139 and a shaft 215 carrying a drive pulley for the belt 166. As the line reaches a transfer channel 206, Fig. 10, the pawl 189 is tripped by a pin 207. The channel 206 is operated by means of a rack 238, Fig. 12, gear 239. pinion, rack 241, lever 258, and a cam 257 on the line shaft. The rack, Fig. 17, is raised by a cord connected to the hub of a pulley 243 on the line shaft, an arm 244 on this shaft carrying a pawl which normally engages a shoulder on the puliey and is tripped by a projection 248. A measuring-slide 249, Fig. 18, having an adjustable leg, is released on operating the lever 192, Fig. 10, and is raised by means of a link 253 and a cam on the line shaft. A pawl 260, Fig. 12, engages the rack 241, to hold the parts in line with the justifying-channel. The ejector delivering the separators is connected to a counting-rack 261, Fig. 18, by links, a rock-shalt 264, and an arm 265 with a feed-pawl. When a line is assembled, a projection on the rack 261, stands opposite one of a series of pins in the slide 249, and, as the latter descends, the pin is pushed out to engage one of a series of dividing-levers 269, which operate on a cross piece 270 carried by a bar 271, operating on an arm of a rock-shaft 274 having a second arm for adjusting a mould-slide 276. The mould proper 278 is carried by a sliding yoke 279, and is movable from a casting position to a position in which the spaces may be ejected into a runway 357, Fig. 12. The yoke 279 is reciprocated from the line shaft. A knife 290 cuts a groove in the justifying-space to facilitate breaking off the jet. The melting-pot 293, Fig. 17, is divided into two compartments, one containing a pump plunger 295 operated from the space shaft, and the other a dipper 298 operated from the line shaft. A preceder head is carried by a slide and supported by a weighted cord, and a follower head is connected to a heavy slide raised by a cord from the pulley 243. The line of type and separators descends until the near projecting end of the first separator engages a support 342, Fig. 12, and the forward end strikes a trigger lever 343, operating a latch releasing a slide on an ejecting-yoke., a projection on the slide engaging a notch on a rack reciprocated from the space shaft, and the yoke releasing the mould pump. The space ejected into the runway 357, Fig. 12, is carried by a pusher 358 on a flexible arm of a rock-shaft operated from the space shaft. The runway is enclosed in a circular rail which is carried by a vertically-movfble post and a stationary circular flanged rail, and is operated by a lever from a lever clamping the slide 276 ; a pin on the rail rests, during the casting, on a cam connected with the slide 276. Finally the follower head pushes the line so that the precader head strikes an arm 378, Fig. 12, and rocks a shaft 379 to withdraw the pawl 260, an arm 380 on the shaft also serving to stop the space shaft. At the commencement of each revolution of the line shaft, the previous line is brought to register with a galley by a blade carried in vertical guides in a slide reciprocated from the line shaft. The line is moved into the galley by a pusher connected to a rack reciprocated from the line shaft. A lead magazine 402, Fig. 18, is arranged with a pusher 404 and rack 405 driven from gear of the line-pusher rack. Mechanism for returning separators to their magazine and ejecting them, applicable also for loading type or ordinary spaces or quads, is shown in Fig. 28. The discarded separators slide down an incline 356 to a platform 430, and are raised thence into the magazine by an elevator-yoke 431, and retained by spring detents 432. A pin 435 extends through a slot in the yoke from a reciprocated slide held in frictional engagement with the yoke by a spring. A stud is pressed forward in the lower part of the slide, and withdrawn by a cam, passing off the cam and against the yoke if the separator is not fully on the platform, but otherwise passing under the yoke to carry it up positively. An ejector normally resting on the top of the uppermost separator in the magazine is in the form of a rack engaging an elongated pinion operated by a rack 417 and linkage from one of the ejectors 125, Fig. 3. This rack 447 also operates the separator counting- device.
